PREGNANCY: Testosterone undecanoate is not recommended for pregnant women or in women who may become pregnant. Testosterone undecanoate causes fetal harm; therefore, it must be avoided.
NURSING MOTHERS: Although it is not known whether testosterone undecanoate enters breast milk, it is not recommended for nursing mothers due to high risks of infant harm and serious adverse events.
